It supports NetFlow, sFlow, IPFIX, J-Flow, NetStream, cflowd, and AppFlow. The product is deployed on premises and lists Android, iOS, Linux, web, and Windows platforms. Its Free Edition costs nothing and covers 2 interfaces. Standard Edition costs $172 a month for 10 interfaces; Professional Edition costs $245 a month for 10 interfaces. Enterprise Edition costs $3,795 a month for 100 interfaces. The listed pricing model is freemium, with a 30-day trial. Interface capacity differs by edition, so the number of interfaces to monitor is central to choosing an option.

ObservabilityOS collects structured logs and supports observability workflows across logs, metrics, and traces. It uses rolling statistical Z-score baselines to flag changes in error rates, latency, and CPU usage, then can use GPT-4 or Claude for incident analysis that describes what happened, why, and a suggested hotfix. Log collection options include a JavaScript/TypeScript SDK and a Docker sidecar for local logs or container output. The ingestion API supports native OTLP HTTP/JSON for existing collectors. Listed integrations include OpenTelemetry, GitHub, Slack, Discord, Microsoft Teams, Docker, Kubernetes, PostgreSQL, and Redis. Incident tools include threaded comments, runbooks, health dashboards, SLOs, and live SSE monitoring. The maker says telemetry is scrubbed before storage and sensitive client data is not sent to external LLMs. Plans include a free developer option, a free source-available self-hosted option, and Pro Cloud at $29/mo. The developer plan allows one service, 500MB of logs monthly, and seven-day retention; Pro Cloud lists 10 services, 10GB monthly, and 30-day retention.
